Far Ultraviolet Spectroscopic Explorer (FUSE)

Mission Background Information
The Far Ultraviolet Spectroscopic Explorer (FUSE) mission provides a new and exciting view of the universe through high resolution astronomical spectroscopy in the far ultraviolet (FUV). FUSE is a NASA-supported mission which launched in 1999. Johns Hopkins University (JHU) has the lead role in developing the overall mission, in collaboration with other universities, and international partners. FUSE was the first in the series of Mid-Explorer missions.

FUSE provides high resolution astronomical spectroscopy between 91nm and 120nm at vastly higher sensitivities than previous missions. The mission provides new insight into the primordial deuterium abundance, the evolution of the inter-galactic medium, the chemical evolution of galaxies, and primordial abundances and physical processes in the Solar System.

University of Colorado/CASA Contributions
The CASA FUSE team was responsible for the payload Spectrograph design and construction. Spectrograph Integration and Test (I&T) was performed at the University of Colorado's Astrophysical Research Laboratories (ARL). Several members of CASA are on the FUSE Science Team, and CASA members have been awarded substantial observing programs with FUSE.
